My colleague Susan Kegley alerted me to a new study in Environmental Science and Technology (ES&T) that illustrates the absurdity of chemically-dependent agriculture — particularly the lengths we'll apparently go to keep the needle in. Scientists are actually studying injecting up to 32,000 lbs/acre of concentrated ammonia into the soil to counteract a fumigant pesticide's ozone-depleting effects.

DDT ceased being the "go to" tool in the malaria fighter's tool box more than 50 years ago when mosquito populations started developing resistance and when better, safer tools began to come online. It's still available today, but the chemical's usefulness is extremely limited. Now, new research shows that in some circumstances spraying DDT is not only ineffective, but it may actually increase malaria transmission.

In my family Thanksgiving means cranberries, sweet potatoes, and green bean casserole. So I decided to check these foods out on WhatsOnMyFood.org. The results weren’t exactly appetizing. Here’s what the USDA found, after washing:

Green beans: 44 different pesticides with the most commonly detected being acephate, a highly neurotoxic organophosphate insecticide. One sample had 200 micrograms of it per 100 gram serving (slightly more than one cup). That may not sound like a lot, but it's twice the EPA's level of concern for children.

The New York Times is reporting that Stephen Johnson, head of the Environmental Protection Agency under Bush, has joined the board of directors of Scotts Miracle-Gro. The company is the world's largest producer of chemicals for the lawn care and garden sectors.
